Exemplary (3 pts) — ‘no question that author understands material in question’
General Approach.  Response addresses the question and states a relevant, fully correct answer;  presents arguments in a logical order;  uses correct style and grammar (no errors).
Comprehension. Response demonstrates a clear and complete understanding of the question;  backs answer with scientific information and justification by using 2 or more ideas, examples and/or arguments that support the answer.

Adequate (2 pts) — ‘author may generally comprehend material, but complete understanding is not evident from the response’
General Approach. Response does not address the question explicitly, although does so indirectly;  answer includes conceptual or factual errors.  States a somewhat relevant and justifiable answer;  presents arguments in a logical order;  uses adequate style and grammar (1-2 errors).
Comprehension. Response demonstrates only limited understanding of question because it does not back conclusions with scientific information and justification;  uses only one idea or example to support the answer.

Needs Improvement (1 pt) — ‘author knows some of words or facts, but response does not illustrate understanding of the concept in question’
General Approach. Response is not relevant to question, but is on topic;  indicates incomplete understanding;  is not clearly or logically organized;  fails to use acceptable style and grammar (two or more errors).
Comprehension. Response does not provide evidence or justification to support answer to the question.
